Leners Param No. 70,669, daad November 5,1867,

MACHINE I'QEHAKING BRICK.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, DANIEL WOODBURY, of Minneapolis, in the county of Hennepin, and State Aof Minne' seta, have invented a new and improved Device for Haking Brick; andI do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specication.

This invention consists in the construction of a machine by which ainumber of bricks may be taken from the yard, (where they have been deposited from the .moulds to dry,) and carried to'and arranged in the pile called a hake." (The operation of thus handling brick is called `by brick-makers haking.)

By the use of this machine the haking is accomplished without handling the brick o'ne by one,.as i8 usually done, as will be hereinafter described.

' In the accompanying plate of drawings my improved device for haking brick is illustrated.

Figure 1 represents a side elevation of themachine, showing the arrangement of parts, vor the manner of its construction.

Figure 2 is an edge view of the same.

Similar letters of reference indicate corresponding parts.

The machine opeates upon the plan of a tongs or grappling-iron, composed of a series of interior grappling arms or clamps, which are controlled in their movement by the main or outside pair. I

. A A represents the main pair of clamps, which-are jointed together ata. B B and C C areointerior clamping-arms, which are attached to AA by pivoted connections, as seen at c c'. They are also pvoted together at d d, and where the two shorter arms are connected there is a central arm, D, which hangs loosely upon its pivot.- E is a guide-plate, which is connected to 'A A by supporting-rods e e.- The ends of the rods e e are turned at right angles, and pass loosely through the guide and the clamps A A, so that the guide-plate adjusts itself to the movements of the machine.

The operation or movement of the machine is controlled by the slide or handle F. This handle forms the *are of a circle, and is made of two plates, connected together byA stud-pins, leaving a space between them, in Vwhich space are arranged rolls nlarkedf, two rolls for each arm of the clamps A A, and between which the arms pass freely. These arms, above the connection a, are of such a shape that when the sliding handle is raised, the lower ends o f the clamps are moved towards the central clamp D, thus grasping the brick. When the handle is lowered, the opposite takes place, the clamp being spread. G is an ear on one of the clamps A,

by which themachine is`lifted from the brick after depositing them on the hake.

In usingthe machine, the clamps are placed between the bricks, as they are arranged on the ground, (edge- Wise,) when the handle F is drawn up, which clamps or grapples the brick with suilicient force to allow of their being carried to and deposited on the hake. By pushing down the sliding handle, the hold upon the brick is loosened, when the brick are brought into line by pushing against'the guideplate E, when the machine is raised, by taking hold of the ear G, and lifting it from the brick.

A side view of the lower end of each of the clamps is seen in g. 2, marked H. What I claim as new, and desire to secure by Letters Patent, is- A machine for haking brick, constructed and operating substantially as herein shown and described.
